Hello,
I''m struggling with this stuff and can''t find an answer so
please advise.
What I''m trying to achieve
@collection has 7 elements
I want to:
- cycle through all those elements
- assign element["smth"] through element["smth3"] to
@data.set1_smth through
@data.set1_smth3
- the last iteration would be assigning element["smth"] to
@data.set7_smthetc
I just don''t seem to grasp how to change @data.set1_smth into @
data.set2_smth etc. when iterating the block.
i = 1
@collection.elements.each do |item|
@data.set1_smth = item.elements["smth"] # obviously @
data.set1_smth should be somehow different
@data.set1_smth2 = item.elements["smth2"]
@data.set1_smth3 = item.elements["smth3"]
i += 1
end
Can anybody help?
I tried @data.send("set" + i + "_smth") but that
didn''t seem to work.
Thanks in advance.
Radek
